Natural Disasters; a Brief Look at Economic Consequences of Drought, Earthquake and Flood during Nasseri Era

The occurrence of natural disasters accounts for one of the most significant developments in the social history of Iran. Despite its strengths in quantity and variety، Iranian historiography can be seriously criticized due to its negligence of describing natural incidents and disasters; these incidents have always been a starting point for many historical developments. Thus، the present research attempts to explore this part of the social history، which was the starting point of many developments، during the ruling of Nassereddin Shah of Qajar (1885-1934). The main question of this research is: To what extent and in what way such incidents as drought، earthquake and flood affected the economic system during the ruling of Nassereddin Shah? To find the answer to this question requires a historical research using descriptive-analytic method. Data collection was carried out using the library method. The findings of the research suggest that this stage of Iran''s history (1264-1313 AH) went through such destructive natural disasters as drought، earthquake and flood. These were followed by the spread of epidemic diseases and a decrease in the population. Still worse، these natural disasters had big impacts on the weakening system of economy and the life of people during the Nasseri era.
